Here is a beautiful song performed by the duet Sašo Gačnik (a.k.a. Svarogov) and Sergey Voytenko. These are famous musicians in Slovenia and Russia.
The piano part is Pianoteq. Enjoy.

Thank you, Niclas! Nice to hear people using Pianoteq with song. Mostly it is as a solo or with orchestra. And here it sounds so clear. I tried to guess which piano.  Often people use Steinway but to me the sound is a bit soft - maybe Steingraeber Warm….? What do you think?
Anyway, a nice gift to start my spare time this evening, the time during which I do not have to work for some hours and can do whatever I like. Thanks!
